So presumably the later OSes would also fit: i.e. XP Pro would allow client installation, and Windows Server 2003 would allow full install.
BTW, the developer edition will install on XP Pro although you should note the following from BOL:
Although the Developer Edition supports all the features of the Enterprise Edition that allow developers to write and test applications that can use the features, the Developer Edition is licensed for use only as a development and test system, not a production server.
